を特徴とする孔版印刷用ステンシルの作製装置。[Claim for Utility Model Registration] By irradiating light onto a processed object in which a translucent heat-sensitive stencil is superimposed on the image surface of the original, the stencil is made to have ink transparency corresponding to the image area of the original. A device for producing a stencil for stencil printing, comprising a flash lamp for forming a through hole and a power supply circuit for causing the flash lamp to emit light, the power supply circuit for causing the flash lamp to emit light. The main capacitor is equipped with an energy supply main capacitor for supplying energy, a switch circuit that controls energization to the main capacitor, and a control circuit that controls the operation of the switch circuit, the control circuit charging the main capacitor. a detection circuit for detecting voltage; and a comparison circuit for supplying an operating signal from the detection circuit to the switch circuit based on a detection signal and a reference voltage signal from the reference voltage circuit to constantize the charging voltage of the main capacitor. The detection signal from the detection circuit or the reference voltage signal from the reference voltage circuit has a level that shifts in the direction of increasing the charging voltage of the main capacitor as the environmental temperature decreases. A device for producing a stencil for stencil printing, characterized by the following.
